The study was based on tools and guidelines provided by Google on web.dev. For the latency measurements, we have ensured that sufficient up- and download speeds were available to the devices at all times: an uplink throughput “at click” of at least 1 Mbps and a downlink throughput “at click” of at least 20 Mbps. We used high-end smartphones connected to the Internet in a controlled environment and had the smartphones request popular content (YouTube, Instagram, Amazon, eBay, Uber, IKEA, and many more) in an automated way. ![]() I will also provide evidence supporting the statement in Figure 1 that latency rarely exceeds 50 ms in advanced 5G and 4G networks.īut first, the background behind Figure 1: both charts show the key results of an in-depth study we have conducted at Ericsson. ![]() ![]() It may explain why some people arrive at different conclusions. I will address some of the key aspects that are often not considered in discussions about latency. If you believe us at Ericsson, then you can stop reading here. The key message of this blog post is shown in the upper chart in Figure 1 and can be formulated like this: Latency hardly impacts smartphone user experience in advanced 5G and 4G networks. Figure 1: Time-to-content is largely determined by speed, not much by latency 1 ![]()
